N91GY will probably be the same thing and one wonders if a warning should have been given by FAA/Cessna although I would think the parking brake would be on the TO checklist since it was not part of the TO warning system.

I don’t have any experience with the type so this is just a curious question….
I see the focus is on the brakes being applied, potentially inadvertently, but is it possible they tried to abort however the thrust levers were stuck at T/O power instead?

Can’t say I’ve never tried to taxi when cleared onto the runway with the parking brake set…….
Hold short for landing traffic…..*parking brake set* ….cleared for immediate take off.
You know, one of those.

I talked to a XL pilot yesterday morning while waiting around the FBO.
I asked him if he had following this mishap. He hadn’t.
When I told him what the prelim had stated he was blown away.
I asked him about his use of the brakes and he said that once leaving the line that he never uses the parking brake unless he is told there will be a long delay for takeoff for example.
